Sunoco Leaded Race Fuels

Standard

Sunoco® Standard™ is a 110 octane leaded race fuel that is commonly used in all forms of motorsports.  It features a comprehensive additive package to enhance shelf life by improving stability and minimizing oxidation.  Sunoco Standard is designed for compression ratios up to about 13:1 in conventional small block V8s with iron heads, and can tolerate higher compression ratios in smaller or more efficient combustion chambers.  It is also a good choice for mild nitrous, turbocharged, or supercharged applications.

As with any gasoline, Sunoco Standard should be stored in opaque, tightly sealed containers and kept where temperatures are stable.  Properly stored, the shelf life of Sunoco Standard is in excess of 2 years.

Maximal

Sunoco Maximal is a 116 octane, extreme performance leaded racing fuel designed for high revving racing engines with high compression ratios.  Maximal’s fast burn rate makes it particularly beneficial in large-bore, large-displacement naturally-aspirated drag racing applications.  It has also proven to be very popular in the highly-stressed naturally-aspirated big blocks used in truck pulling.  Sunoco Maximal is very resistant to vapor lock, ensuring consistent fuel metering between passes.

Sunoco Maximal is for off-road and racing use only.  It contains additives to enhance stability and minimize oxidative effects.  As with any gasoline, Maximal should be stored in opaque, tightly sealed containers where temperatures are stable.  Handled under such conditions, the shelf life of Sunoco Maximal is 2 years or more.

MaxNOS

Sunoco MaxNOS is the fuel of choice for extreme performance applications where “power adders” such as nitrous, superchargers, and turbochargers are utilized.  Sunoco Race Fuels engineers added components to this fuel to be able to withstand ultra high pressure / high temperature combustion chamber conditions.  MaxNOS was tested in a variety of drag racing applications ranging from mega-boost turbocharged small engines to multi-stage nitrous systems on mountain motors.  It’s also a great fuel for supercharged pulling trucks.

Sunoco MaxNOS is for off-road and racing use only.  It contains additives to enhance stability and minimize oxidative effects.  As with any gasoline, MaxNOS should be stored in opaque, tightly sealed containers where temperatures are stable.  Handled under such conditions, the shelf life of Sunoco MaxNOS is 3 years or more.

EX02

Sunoco EXO2 is a very highly oxygenated race fuel.  EXO2 is beneficial in crate engines, two-barrel engines, and racing classes with cylinder head limitations, as well as engines running at higher elevations.

Due to its high oxygen content, Sunoco EXO2 requires a richer air/fuel mixture.  Using EXO2 without proper air/fuel mixture changes can lean out your engine.  Please consult the Stoichiometric Air/Fuel Ratio data in the table below.  Since non-oxygenated race fuels typically have a stoichiometric air/fuel ratio of 14.6:1 to 15.0:1, you may need to richen your fuel mixture by 10 to 15 percent when using EXO2.

As with any gasoline, Sunoco EXO2 should be stored in opaque, tightly sealed containers and kept where temperatures are stable.  Drum pumps should be removed immediately after use.  Properly stored, the shelf life of Sunoco EXO2 is one to two years.
